Parallel, Perpendicular and Intersecting Lines

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They are always the same distance apart.

Front

What are perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

What are intersecting lines?

Back

Intersecting lines are lines that cross each other at any angle.

Front

Can parallel lines ever meet?

Back

No, parallel lines never meet, no matter how far they are extended.

Front

What is an example of parallel lines?

Back

Railroad tracks are an example of parallel lines.

Front

What is an example of perpendicular lines?

Back

The corner of a square or rectangle forms perpendicular lines.

Front

What is an example of intersecting lines?

Back

The letter 'X' is formed by two intersecting lines.

Front

How can you identify parallel lines?

Back

You can identify parallel lines by checking if they are always the same distance apart.

Front

How can you identify perpendicular lines?

Back

You can identify perpendicular lines by checking if they form a right angle (90 degrees) when they intersect.

Front

How can you identify intersecting lines?

Back

You can identify intersecting lines by checking if they cross each other at any angle.
